|
* When a function contains a lot of constants and try-catch is used after
|
|
* them, the trycatch variable name constant will no longer fit into the
|
|
* 'C' slot of the opcode.
|
|
*
|
|
* Duktape 0.12.0 would ignore this and the constant would end up pointing
|
|
* to an incorrect constant, which causes unsafe behavior and may trigger
|
|
* an assert failure. Duktape 1.0.0 has a safety fix to detect this case
|
|
* and fail compilation with an internal error.
|
|
*
|
|
* The actual fix probably needs a change in the opcode semantics to better
|
|
* support shuffling.
